14 Claims. '(Cl. 211-2) The present invention relates to foldable table structures and to a novel foldable structure selectively usable as a table and as a storage rack for one or more additional foldable tables.

As will be understood, there are numerous tray tables now on the market, which tray tables usually comprise a pair of pivotally connected inverted 'U-shaped frame or leg structures and a tray detachably connected with the frame or leg structures in a manner such that the leg structures and tray may be folded or collapsed from a set-up" condition to a substantially flattened condition Such tray tables are frequently sold in sets of four or more and with a rack on which the tray tables may be stored when they are in a collapsed condition. It has heretofore been suggested that such a rack could be formed so that it could also be used in combination with a tray to provide another tray table in the set. While such atray table and rack set has met with wide commercial acceptance, it is an important object of the presentinventionto provide a novel folding or collapsible table set including a novel and improved structure which may be selectively used as a storage rack for folded tray tables and the like and as a table.

More specifically, it is an important object of the present invention to provide a novel combined storage rack and table structure which may be manipulated between a relatively spread-out condition in which it is used as a table and a relatively collapsedor compact conditionin which it is used as a rack whereby the amount of storage space required by the structure is minimized.

Another important object of the presentinvention is to provide a novel structure which may selectively be used as a table or as a storage rack for tray "tables and the like, which structure maybe manipulated so as to increase the overall height thereof when it is to be used as a storage rack so that an uppermost part thereof is presented at a height which facilitates manual handling of the structure and moving of the structure from place to place.

A more specific object of the present invention is to provide a novel structure which may be selectively used as a table and as a storage rack for foldable tray tables and the like, which structure maybe manipulated so as to provide a relatively low table which may serve as a coffee table and the like.

Still another object of the present invention is to provide a novel combined rack and table structure of the above described type which is provided with wheels so that it may be easily moved both when it is-functioning as a table and when it is functioning as a storage rack.

Still another object of the present invention is to provide a novel combined'storage rack and foldable table of the above described type which may be quickly and easily manipulated between the arrangements in which it will function as a table and as a storagerack.

A more specific object 'of the presentinvention is to United States Patent provide a 'novel set including :a plurality of foldable tray tables and the like and a combined table and rack structure, which set is constructed so that when the tray tables are in a folded condition and are assembled on the rack, the rack may be alternatively tilted in opposite directions and pulled or rolled to any desired location without danger of the tray tables falling from the rack.

Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings wherein:

Fig.9 is a perspective view showing one of the tables of the set in a set-up condition.

Referring now more specifically to-the drawingswherein like parts are designated by thesame numerals throughout the various figures, a set 10 incorporating features of the present invention includes one or more foldable tray tables 12 and a unit 14 which is adapted alternately and selectively to 'be used as a storage rack for the-tray tables '12, and as a table. 'In the embodiment shown, four tray tables '12 are provided, but it will be understood that the number of tray tables may be varied as desired.

Each tray table 12 includes inverted U-shaped frames 16 and 18 and a tray 20. The frame or leg structure 1-6 comprises opposite sidev or leg portions 22 and 24 which are integrally joined at their upper ends by a transverse or bight portion 26. The frame or leg structure 18 is substantially identical to the structure 16 in that-itincludes opposite side or leg portions 28 and 30 having their upper ends integrally joined by a bight portion 32. However the'bight.portion.32 is slightly'longer than the bight portion 26 so "that the leg portions 28 and'30 are adapted to extend along the outer sides of or, in other words, to embrace the leg portions 22 and 24.

The leg portions 22 and 28 are connected intermediate their ends by suitable pivot means 34 and the leg portions 24 and 30 are similarly connected-by pivot-me'ans'36. The pivotal connections are such that the frame or l-leg structures '16 and 18 may be manipulated or :pivoted betweenthe opened and crossed positionsshown'in Fig. 9 and the closed and-substantially.parallelpositionsshown in Figs. 1, 2 and 4. a I

Pairs ofclip elements 38 and 40 and 42 and 44 are riveted orotherwise suitably'secured to the under .surface of the tabletop or tray 20. 'Theclip-elementsfis and 40 are adapted to be connected 'to thebight portion 26 and-the clip elements'42 and 44 are'adapted tozbe connected to the bight portion. 32-.when theztray table. iszin the set-up condition: shown inxFig.;9. 3.'I.'he:quick;release or snap-on c1ip elements38iand .40. are. also: adapted =zto be detached from the bight portion 26 so as to enable the frame or leg structures 16 and 18 to be folded from the open and crossed positions shown in Fig. 9 to the collapsed positions shown in Figs. 1, 2 and 4. The clip elements 42 and 44 are such that the tray or tabletop 20 may be pivoted around the bight portion 32 so that the tray will lie substantially flat against the folded or collapsed leg structures as shown in Figs. 1, 2 and 4. In addition, the clip elements 42 and 44 may be identical to the elements 38 and 40 as is contemplated in the present disclosure so that the tray may be entirely removed from the leg structures if desired.

As indicated hereinabove, the unit 14 is constructed in accordance with an important feature of the present invention so that it may selectively be used as a relatively compact and upright storage rack for the tray tables 12 and as a table. The unit 14 comprises a first generally U-shaped frame or leg structure 46 having relatively long opposite side or leg portions 48 and 50. Upper ends of the leg portions 48 and 50 are joined by a transverse or bight portion 52. In the embodiment shown the leg portions 48 and 50 are substantially straight and are disposed ina common plane while the bight portion 52 is inclined forwardly with respect to the plane of the leg portions 48 and 50, for a purpose discussed below.

The unit 14 also includes a second inverted generally U-shaped frame or leg structure 54 having opposite side or leg portions 56 and 58 having their upper ends joined by a transverse or bight portion 60. It will be noted that the width of the bight portion 60 is less than the width of the bight portion 52 so that the leg portions 56 and 58 extend within the leg portions 48 and 50. Intermediate sections of the leg portions 56 and 58 are respectively pivotally connected to the leg portions 48 and 50 by suitable pin means 62 and 64 in a manner such that they are adapted to lie substantially in the common plane of the leg portions 48 and 50 when the unit 46 is in a condition to serve as a storage rack for the tray tables, as shown in Figs. 1-5. As shown best in Fig. 4, this plane is inclined at a substantial acute angle from the vertical. Lower end sections 66 and 68 of the leg portions 56 and 58 are bent so that they extend rearwardly and ate relatively sharp angle from the common plane of the leg portions 48 and 50 so that the lower terminal ends of the sections 66 and 68 spaced substantially from the lower terminal ends of the leg portions 48 and 50. Upper end sections 70 and 72 of the leg portions 56 and 58 extend from the intermediate sections forwardly and at a relatively sharp angle from the common plane of the leg portions 48 and 50 for the purpose described more in detail below. Preferably a transverse frame member 74 is positioned between and is securedto the lower end sections 66 and 68 of the leg portions 56 and 58.

The unit 14 is provided with a tabletop member or tray 76. Angle brackets 78 and 80 are secured to the under side of the tabletop or tray 76 adjacent opposite side edges and one end thereof, as shown best inFigs. 3 and 5, which brackets are also respectively pivotally connected to leg portions 48 and 50 by suitable pivot 7 pin means 82 and 84. With this arrangement the tabletop member or tray 76 has one end portion permanently and pivotally connected to the leg portions 48 and 50 of the frame structure 46 so that the tabletop may be swung from the collapsed position shown in Figs. 1-5 to the open position shown in Fig. 6.

A transverse frame member 86 extends between and is secured to the leg portions 48 and 50 at a location slightly above the point at which the lower end sections 66 and 68 of the leg portions 56 and 58 are bent rearwardly. This location is also adjacent to but spaced upwardly from the lower end edge of the tabletop or tray'member 76 when the tray member is in the collapsed position. Clip members 88 and '90 are riveted or otherwise secured to the tabletop member or tray 76 at a location so that they are adapted to engage the transverse frame member 86. These resilient snap-on type clip members are similar or identical to the clip members of the folding tray tables 12 and they are adapted to be snapped around the transverse frame member 86 for releasably holding the tabletop member 76 in the folded or collapsed position substantially parallel to the leg portions 48 and 50, as shown best in Fig. 4. In certain modified structures an additional transverse frame member and clips similar to the member 86 and clips I 88 and 90 may be used in place of the brackets 78 and 80. However, the brackets are preferred since they provide clearance in a simple and economical manner for enabling the leg structures 46 and 54 to be manipulated to and from the positions shown in Figs. 1 and 6.

It will be noted that the transverse frame member 86 which in the embodiment shown is tubular, has opposite flattened end portions 92 and 94 secured to the back sides of the leg portions 48 and 50 so as to provide sufiicient clearance for the intermediate sections of the leg portions 56 and 58 to enable such intermediate sections to be positioned substantially parallel to the leg portions 48 and 50. It will also be noted that these flattened end portions of the transverse frame member provide stops for limiting pivotal movement of the frame or leg structures 46 and 54 relative to each other and about the common axis of pivot pins 62 and 64 when the leg or frame structures are in the collapsed and upstanding storage rack providing positions shown in Figs. 1-5.

Referring particularly to Figs. 7 and 8, the manner in which the frame or leg structures '46 and 54 of the unit 14 may be manipulated between the collapsed and upstanding rack providing positions and the opened table providing positions will now be described. Assuming that theparts are in the fully collapsed and upstanding position shown in the solid lines in Fig. 7, an operator may initiate the manipulation of the structure toward the open condition by grasping the bight portions 52 and 60 and relatively pivoting the frame or leg structures 46 and 54 about the pivot pins 62 and 64 and in the direction of the arrows. In other words, the frame structure 46 will be pivoted in a counterclockwise direction as viewed in Fig. 7 and the frame structure 54 will be pivoted in a clockwise direction. Continued movement of the frame structures will cause them to pass through the relative positions shown in broken lines in Fig. 7 and in broken lines in Fig. 8 to the full line opened position shown in solid lines in Fig. 8. When the frame structures have been shifted to the full line opened position, it is merely necessary to snap the clip members 88 and 90 onto the bight portion 60 in order to complete the assembly of the table. It will be noted that the overall width of the unit 14 in the table providing arrangement shown in solid lines in Fig. 8 is substantially more than twice the overall width of the unit in the fully collapsed and upstanding condition shown in solid lines in Fig. 7. In other words, it is clear that the unit 14 in its collapsed condition is relatively compact and requires less than one-half of the floor space for storage purposes and the like than would be the case if it were necessary to store the unit in its fully opened condition.

It will be observed that in order to enable the tabletop member or'tray 76 to be folded to a collapsed position substantially parallel to the leg portions 40 and 50 as shown best in Fig. 7, at least the lower end portion of the tabletop or tray 76 is provided with a width less than the distance between the lower end sections 66 and 68 of the leg portions 56 and 58 so that the end of the table may project between the leg sections as shown in Figs. 1-5 and 7. However, in order to facilitate opening of the unit into a table, the top member or tray 76 may be provided with marginal portions 96 and 98 which extend laterally outwardly at least sutficiently to overlie the leg portions 56 and 58. As a result, when'the frame or leg structures seat-mes 46' and 54 are pivoted from the fully collapsed positioh shown in solid lines in Fig. 7, the leg portions 56 and 58 push against the marginal portions 96 and 98 of the tray 76'as shown in broken lines in Fig. 7 sufficiently to cause the spring clips 88 and 90 to be disconnected automatically from the transverse frame member 86. Further movement of the frame structures automatically swings the tabletop or tray member 76 toward the desired hori- Zontal position as shown in Figs. 7 and 8. It will be noted that the height of the tabletop member or tray 76 as shown in solid lines in Fig. 8 is substantially less than the overall height of the unit 14 in its collapsed and upright condition shown in solid lines in Fig. 7. In fact, in the embodiment shown, the height of the tabletop 76 is substantially less than the height of the tray tables 12, so that the table provided by the unit 14 may function as a relatively low coffee or serving table or the like.

When it is desired to store the set comprising the tray tables 12 and the unit 14, the tray tables are folded or collapsed from the condition shown in Fig. 9 to the con- Idition shown in Figs. 1, 2 and 4, and the unit 14 is collapsed from the condition shown in Fig. 6 and in solid lines in Fig. 8 to the condition shown in Figs. 1-5 and in the solid lines in Fig. 7. While it is possible to disconnect the trays of the tray tables from either of their associated bight portions 26 or 32, the trays are preferably disconnected from their associated bight portions 26. Thus, when the tray tables are folded, as shown in Figs. 1, 2 and 4, the bight portions 26 of the generally U- shaped frame or leg structure 16 will be located at the lower ends of the folded table structures and the free ends of the leg portions 28 and 30 of the generally U- shaped frame or leg means 18 will project downwardly. In association with this preferred arrangement of the collapsed tray tables, it is to be noted that the width of the generally U-shaped frame or leg structure 16 is substantially identical to the width of the frame or leg structure 46 of the unit 14 so that the leg portions 22 and 24 of the generally U-shaped structure 16 are adapted to overlie directly the leg portions 48 and 50 and to be either directly or indirectly supported thereby. At the same time it is to be noted that the widthof the inverted U-shaped frame or leg structures 18 is slightly greater than the width of the frame or leg structure 46. As a result, when the tray tables are stacked on the rack in the manner shown in Figs. 1, 2 and 4, at least the lower end portions of the legs 28 and 30 of the lowermost tray table will extend along the outer side surfaces of and embrace the leg portions 48 and 50 so that the lowermost tray table is effectively locked against twisting or turning relative to the rack. In addition, the lower end portions of the legs 28 and 30 of each succeeding tray table embrace the frame structure 16 of the next immediately adjacent and lower tray table against which it rests so that all of the tray tables are effectively interlocked against turning and twisting with respect to each other and the rack.

As will be understood, after the tray tables 12 are folded, it is merely necessary to position them so that the lower edges of their trays overlie the upper end portions 70 and 72 of the frame or leg structure 54 of the rack in order to assemble the tray tables with the rack. The first tray table will slide down the leg sections or portions 70 and 72 until it rests firmly against and is supported by the generally upstanding but substantially rearwardly inclined legs 48 and 50 as well as the leg sections 70 and 72. The remaining tray tables will, of course, be similarly supported by the leg sections 70 and 72 and indirectly supported by the leg portions 48 and 50 through the preceding tray tables.

As indicated above, the bight portion 52 of the inverted generally U-shaped frame or leg structure 46 is inclined forwardly with respect to the leg portions 48 and 50.

is-such that it presents an intermediate handle section 100 6 at a convenient height and location above the upper edge of the upper most tray table and also generallycentrally between front and back sides of the assembly provided by the tray tables and the rack. Withthis arrangement the rack may be easily grasped by the handle section and picked up, tilted rearwardly or even tilted forwardly in order to accomplish transportation of the assembly from one location to another. It is obvious that the folded tray tables'are supported by the legportions 48 and 50 in a manner which precludes any possibility of the tray tables falling from the rack when the rack is tilted rearwardly for movement from one place to another. It is also to be noted that the tray tables are adequately supported so that they will not fall from the rack when the rack is tilted forwardly a reasonable amountduring transportation from one place to another. In this connection it will be noted that the leg sections 70 and 72 are normally inclined upwardly from the horizontal at a substantial angle so as to prevent the tray tables from sliding forwardly even though the rack is tipped forwardly, and the above described interengagement between the bight portions 26 and leg portions 22 and 24 with each other and with the rack and the interlocking engagement of the lower end portions of the legs28 and 30 with the rack and the adjacent tray tables prevents the tray tables from tilting or pivoting around the lower edges of their trays.

In order further to facilitate movement of the rack from place to place and also to enable the unit 14 to be used as a mobile serving table, wheels 102 and 104 are respectively connected with the lower ends of the leg portions 48 and 50 and similar wheels 106 and 108 are connected with lower end portions of leg sections '66 and 68. It will be noted that the wheels 102 and 104 are rotatably mounted on pins or axles 110 and 112 which are fixed to the lower ends of the leg portions 48 and 50 and extend laterally outwardly therefrom so that these wheels are disposed outwardly of their associated leg portions. The wheels 106 and 108 on their other hand, are disposed laterally inwardly of their associated leg portions and they are rotatably mounted on pins or shafts 114 and 116 respectively. Thus the wheels are disposed so as to avoid interference with each other during manipulation of the leg or frame structures 46 and 54 to and from the collapsed rack and open table arrangements. It will be noted that when the unit 14 is set up as a table, the bight portion 52 extends laterally and downwardly to position the handle section so that it may be easily used for manipulating the table without obstructing access to the tabletop.

While the preferred embodiment of the present invention has been shown and described herein, it is obvious that many structural details may be changed Without departing from the spirit and scope of the appended claims.
